WILLIAIVI GREENFIELD, OF PHILADELPEIA, PENNSYLVANIA.

ELECTRIC GAS LIGHTER.

Application filed Felruary 12, 1824. Serial No. 692,216.

To all whom t 'may concern.'

Be it known that I, TILLIAM GnEENrinLp, a citizen of Hungary (having declared his intention of becoming a citizen of the United States), residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new l and useful Improvements in Electric Gas Lighters, of which the following is a specification.

My invention relates to elect-ric gas lighters and its objects are to provide a gas lighter of simple and durable const-ruction which will light the gas in a gas range by rubbing an electrode over the gas burner to produce electric sparks, and to provide a handlefor the electrode which will protect it against contact with other parts of the range when not in use.

These objects, and other advantage-ous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a central section through a handle constructed in accordance with my invention,

Figure 2 a section on line 2 2 of Figure 1, and

Figure 3 a diagrammatic view of the electrical connections to the handle.

Referring to the drawings, 1 indicates a gas range, 2 the burners and 3 the pipe connecting the burners and leading to the ground Il. My improved handle 5 houses an elect-rode which is connected by a wire 6 to an electric lamp 7 which is connected at 8 to one pole of the house current. The construction of the handle includes a casing 9 of insulating material, preferably wood; a terminal plate 10 having an electrode 11 secured thereto; a cap 12 of insulating material screwed onto the casing and securing the terminal plate therebetween, and a gua-rd sleeve 13, preferably of porcelain, slidable on the electrode and within the cap. The guard sleeve normally extends over an end 14 ofthe electrode and is provided with a shoulder 15 which abuts the inside of the cap to prevent outward movement of the sleeve. A spring 16 is interposed -between sleeve 13 and terminal plate 10 to keep the sleeve over end 14 of the electrode. The terminal plate is provided with fastening holes 17 and 18 through which passes the conduit wire 6 which is electrically connected to the plate by a screw 19. It is readily seen that by passing the conduit wire 6 through holes 17 and 18 as shown in Figures 1 and 2, pulling or jerking the wire will not disrupt its electrical connection with the terminal plate.

In producing electric sparks to light the gas, the current passes from the connection 8 of one. pole of the house current through lamp 7, conduit 6, electrode 11, burner 2, gas pipe 3 to the ground 4. The ground, which is usually connected to the other pole of the house current, conducts the current to the other pole to complete the circuit.

To light the gas burner, guard sleeve 13 is brought into Contact with the burner and pressed inward until the end 14 of the electrode engages the burner. The electro-de is then rubbed o-ver the burner and the gas turned on. Lamp 7 prevents the fuse from blowing out when the circuit is completed and thereby eliminates high resistance transformers.

By connecting and making a gas lighter as above described the electrode is protected against contact with the gas range when not in use, and the fuses, for the house current, will not blow out.

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the sp-irit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come Wthin the scopev of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. An electric gas lighter including a handle; an electrode having one end secured in and the other end extending out of the handle; a conduit wire electrically connected with the electrode and within the handle, and a guard sleeve slidable on the free end of the electrode.

2. An electric gas lighter Iincluding a handle; an electrode having one end secured in and the other end extending out o-f the handle; a conduit wire electrically connected to the electrode; a guard sleeve slidable on the free end of the electrode, and resilient means between the handle and the sleeve for keeping the sleeve over the end of the electrode.

8. An electric gas lighter including a handle; an electrode having one end secured in and the other end extending out of the handle; a conduit wire electrically connected to the electrode; a guard sleeve slidahle on the free end of the electrode, and a coiled spring around the elect-rode between the handle and the sleeve for keeping the sleeve over the end of the electroce.

4. An electric gas lighter including a casing; an elect-rede having one end secured in the casing; a cap secured to the handle and enclosing part of the electrode; a conduit wire passing through the casing and electrically connected to the electrode; a guard sleeve slidable on the electrode and in the cap, and resilient means for keeping the guard sleeve over the end of the electrode.

5. An electric gas lighter including a casing; a terminal plate; an electrode secured to the plate; a cap securing the plate to the casing and enclosing part of the electrode; a guard sleeve slidable on the electrode and in the cap, and resilient means for keeping the guard sleeve over the end of the elect-rode.

6. An electric 0as lighter including a casing; a termina plate having fastening holes; an electrode secured to the plate; a conduitl wire passing through the holes and electrically connected to the plate; a cap securing the plate to the handle and enclosing part of the electrode; a guard sleeve slidalole on the electrode and in the cap, and resilient means for keeping the guard sleeve over the end of the electrode.

7. An electric gas lighter including a easing; a terminal plate; a cap securing the terminal plate to the casing; an electrode secured to the plate and extending out of the cap; a guard sleeve slidable on the electrode and in the cap; a. shoulder on the sleeve engaging the cap for preventing eutward movement, and resilient means for keeping the sleeve over the end of the electrode.

In testimony whereoil I have signed my name to this specification.

WILLIAM GREENFIELD.
